THE AUCHENORRHYNCHOUS HOMOPTERA. 149 



tured, black, with a subsutural and submarginal fulvous slightly raised 

 band, joined at the apex. Length 7 miUim. 



Head closely punctured, with a smooth narrow central line ; frontal 

 tubercles distinct ; antennae extending nearly to tlie middle of the 

 elytra, black, the lower three joints more or less fulvous below, 

 terminal joints shorter than the intermediate ones ; thorax twice as 

 broad as long, narrowed in front, the sides rather strongly rounded, 

 narrowly margined, the anterior angles not produced, the surface 

 i-eddish fulvous, with a broad transverse black band at the middle, not 

 quite extending to the lateral margins, this band closely and finely 

 punctured, the fulvous portion nearly impunctate ; scutellum much 

 broader than long, black, impunctate ; elytra extremely closely and 

 distinctly punctured, black, with two narrow dark fulvous bands, one 

 near the suture and about as wide as the black sutural interstice, the 

 other near the lateral margin, of the same width and joined at the 

 apex to the subsutural band, both these bands are somewhat convex 

 or semicostate ; the elytral epipleurae, the entire under side and legs 

 black, finely clothed with grey pvibescence ; the flanks of the thorax 

 and the presternum fulvous. 



Hah. — Venezuela. 



The thoracic black and closely punctured band, the very close 

 punctuation of the elytra and the semicostate fulvous bands will 

 distinguish this species (of which three specimens are before me) 

 from any of its congeners. 



ON THE MORPHOLOGY AND CLASSIFICATION OF THE 

 AUCHENORRHYNCHOUS HOMOPTERA. 



By Dr. H. J. Hansen. c^ 



(Continued h-om vol. xxxiii. p. 334.) 



The'^CercopidsB thus differ by the metasternum, by the form 

 and articulation of the posterior coxse (partly also by their size), 

 by the quality of the articulation between the trochanters and 

 femora, and by the presence of the femoral protuberance just 

 mentioned — from the following and preceding families, and they 

 form in many respects a transition between them and the 

 extremely remarkable Fulgoridae. 



■, 3. Jassida. — The metasternum is strongly chitinined, and 

 forms merely a narrow transverse belt, except at the middle line, 

 where it sends a longitudinal narrow plate backwards between the 

 posterior coxae. These are very large, and their articidatton extends 

 right across to the lateral margin of the body, and nearly to 

 the middle line. Their free distal part is proportionately 

 moderately short, and directed downwards, backwards, and to- 

 wards the middle plane, so that the interior angles of the two 

 C0X8B approach together in the middle line ; the trochantins are
